[texts]Prototyping a Wireless Sensor Node using FPGA for Mines Safety Application
The sensor nodes in a wireless sensor network are normally microcontroller based which are having limited computational capability related to various applications. This paper describes the selection, specification and realization of a wireless sensor node using the field programmable gate array (FPGA) based architecture for an early detection of hazards (e.g fire and gas-leak ) in mines area. The FPGAs in it’s place are more efficient for complex computations in compare to microcontrollers, wh...

 Wireless sensor network (WSN) is becomingprogressively important and challenging research area. AWireless sensor network (WSN) consists of spatiallydistributed autonomous sensors to monitor physical andenvironmental conditions and to co-operatively pass their datathrough the network to a main location. Wireless sensorconsists of small low cost sensor nodes, having a limitedtransmission range and their processing, storage capabilitiesand energy resources are limited...

[texts]Energy Efficient Data Transmission through Relay Nodes in Wireless Sensor Networks
In a Wireless Sensor Network (WSN) having a singlesink, information is given to the distant nodes from beaconsby overhearing. Since it is out of the communication range,information is not sent directly to the static sink (SS). If adistant node is not able to communicate directly, then it shouldsend its own packet to another node which is closer to theBase Station (BS) so that the received packets are relayed tothe BS by this node...

[texts]1. Electronics IJECE Design And Implementation Of A. C. Khetre ( 1)
Due to the speed of Indian economic development we can also see the resulting speeding-up the contamination and damage to the water environment, Peoples also responsible who throw the garbage material in water due to which it is polluted. To overcome all this water environmental monitoring system based on a wireless sensor network developed. It consists of three parts data base station, data monitoring nodes and remote monitoring center...
